In the past fifty years or so, the growth of the population has boomed and has turned into overpopulation. By 2100, the population is on track to hit 10.8 billion, according to the United Nations. Increasing global population strains resources, leading to higher demand for food, water, housing, energy, healthcare, and transportation. This consumption contributes to ecological degradation, conflicts, and the risk of large-scale disasters like pandemics. https://www.dw.com/en/five-of-the-worlds-biggest-environmental-problems/a-35915705 (2019) animals Global environmental issues fat-home 5 Deforestation Habi plants for Species-rich wild forests are being destroyed, especially in the tropics, often to make way for cattle ranching, soybean or palm oil plantations, or other only one type of specie a etype of agricultural monocultures. - crop About 7.3 million hectares (18 million acres) of forest are destroyed each year, mostly in the tropics. Tropical forests used to cover about 15 percent of the planet's land area; they're now down to 6 or 7 percent. Much of this remainder has been degraded by logging or burning. par hish biodiversity tropical Rainforest > 15a - o Bhut n a neutral https://www.dw.com/en/five-of-the-worlds-biggest-environmental-problems/a-35915705 (2019) Global environmental issues as 6 Water Pollution ↑ NtPebphicatio Water pollution occurs when harmful substances— often chemicals or microorganisms—contaminate a groundwater stream, river, lake, ocean, aquifer, or other body of - water, degrading water quality and rendering it toxic to humans or the environment. Water pollution originates from industrial discharge of chemicals, runoff of agricultural pesticides and domestic water water waste, inadequate municipal sewage treatment, -- accidental oil spills, and the discharge of toxins from mining activities https://www.dw.com/en/five-of-the-worlds-biggest-environmental-problems/a-35915705 (2019) Global environmental issues perdumpingth react 7 Waste perficiate - Solid waste management is a critical global environmental issue that pertains to the accumulation and improper disposal of various forms of solid waste. Solid waste, results from rapid population growth, urbanization, industrial activities, consumerism, and inadequate waste management infrastructure. They drive increased waste generation, concentrated urban waste, hazardous industrial waste, excessive consumption, and poor disposal practice. i die plas https://www.dw.com/en/five-of-the-worlds-biggest-environmental-problems/a-35915705 (2016) Global environmental issues 8 Air pollution and climate change it cool , potwal gas > - energy Hydrocarbon - Burning of fossil fuels, deforestation for agriculture, - and industrial activities have pushed up atmospheric CO2 concentrations from 280 parts per million (ppm) 200 years ago, to about 400 ppm in nowadays (NOAA, 2020) Carbon overloading is only one form of air pollution caused by burning coal, oil, gas and wood. World Health Organization recently estimated that one in nine deaths in 2012 were attributable to diseases caused by carcinogens and other poisons in polluted - air. concer https://www.dw.com/en/five-of-the-worlds-biggest-environmental-problems/a-35915705 (2019) Global environmental issues 9 CO2 CHy , 12 goses , nitrous Climate change > - Green house Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun’s activity or large volcanic eruptions. But since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels like coal, oil and gas. Climate change effects include extreme weather events, > cause float - rising temperatures, sea-level rise, changing precipitation patterns, ecosystem disruptions, risks to agriculture and food security, and health impacts. Addressing these effects requires mitigation, adaptation, sustainable practices, and international cooperation. https://earthobservatory.nasa.gov/world-of-change/global-temperatures 10 What is the solutions? !!! Sustainability & Sustainable development !!! thing you lifeof living billion 11 Sustainability earth-3 5. on “Sustainability is the ability of the earth’s various natural systems and human cultural systems and economies to survive and adapt to changing environmental term conditions indefinitely.” for long long breaor & - Originally it came from forestry, fisheries, and groundwater, which dealt with quantities such as “maximum sustainable cut,” “maximum sustainable yield,” and “maximum sustainable pumping rate.” Ex: How many trees can we cut and still have forest growth? How many fish can we take and still have a fishery functioning at the end? How much ground water can we draw and still have a viable aquifer at the end of the pumping period? In cut trees plant 10 trees Sustainability a 12 future tir Sustainability also means enduring into the long-term future; it refers to - systems and processes that are able to operate and persist on their own over long periods of time. Living sustainably means living off earth’s natural income without reduce the amounts destroy eg : water is polluted depleting or degrading the natural capital that supplies it. -- Sustainability is the potential for long-term maintenance of well being, which has environmental, economic, and social dimensions. clean > - good health > - good quality of life Rogers, Peter P., Kazi F.

SUSTAINABILITY PRINCIPLES 36 People: End poverty, hunger, and inequality while ensuring dignity, equality, and a healthy environment. Planet: Protect the planet through sustainable consumption, production, resource management, and urgent climate action. ste Prosperity: Enable prosperous lives and harmonize economic, social, and technological progress with nature. 1-1 sace https://www.sdg.services/principles.html SUSTAINABILITY PRINCIPLES 37 Peace: Foster peaceful, inclusive societies free from fear and violence, recognizing the interlinkage between peace and sustainable SDGIS development. Partnership: Mobilize resources and strengthen global solidarity through a revitalized Global Partnership for Sustainable Development, involving all countries, stakeholders, and people. https://www.sdg.services/principles.html SUSTAINABILITY PRINCIPLES 38 39 Recent global measures (MDGs) In 2000, members of the United Nations (UN) adopted a set of goals aimed at halving extreme poverty in all its forms, including hunger, illiteracy, and disease, by 2015. The agreement established a set of 8 Millennium Development Goals (MDGs). Despite not reaching these goals by 2015, they drew the world’s attention to the challenges of extreme poverty, generate new partnerships, and mobilize global efforts. 40 Latest global measures (SDGs) In 2015, world leaders adopted a new set of goals: the Sustainable Development Goals (SDGs). Working groups and stakeholders developed a system of 17 goals with 169 measurable targets and indicators. Rather than being written by a few specialists, they were developed by stakeholders from both developed and developing countries and agreed upon by consensus. https://sustainabledevelopment.un.org/ 41 - - - v - 17 Sustainable Development Goals 42 43 Environmentally sustainable society In order to live sustainably, one must live off the natural resources without depleting or degrading the natural capital that supplies these natural resources By living only on the natural income and not depleting the natural capital, society moves from an unsustainable lifestyle to a sustainable one Earth’s natural capital provides natural income: renewable resources such as plants, animals, soil, and clean water and air “We Must Protect Our Natural Capital and Live Off of Its Income” 44 A more sustainable future is possible Given enough time, most degraded environments can recover – but many will take hundreds or thousands of years to recover Time is our most scarce resource However, 5-10% of a population that changes can make a difference Changes can occur in a shorter time than previously thought Progress of Sustainable Development Goals in ASEAN 45 Proportion of population living below the national poverty line in ASEAN An average of 13.0 per 100 people were living below the countries’ poverty lines in 2018.

There remain wide gaps among member states in achieving maternal health. The 2022 ASEAN SDG Snapshot Report Progress of Sustainable Development Goals in ASEAN 49 Renewable energy share in the total final energy consumption in ASEAN Share of renewable energy in the total final energy consumption in the region was nearly unchanged from 7.47 to 8.46% between 2016 and 2020. Philippines and Vietnam had the highest shares in renewable energy sources. The 2022 ASEAN SDG Snapshot Report 50 References 1.Rogers, Peter P., Kazi F. Jalal, and John A. Boyd.
