Environmental Protection Overview

Environmental Protection Overview

• Environmental protection encompasses practices and policies aimed at safeguarding ecosystems, mitigating human impact, and ensuring resource sustainability for future generations.
• The urgency for environmental protection has increased due to climate change, deforestation, pollution, and biodiversity loss.

Scope of Environmental Degradation

• Human activities have substantially impacted Earth's ecosystems, especially since the Industrial Revolution.
• Climate change is primarily driven by greenhouse gases (GHGs): carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
• Global temperatures have risen by approximately 1.1°C since the pre-industrial period (1850–1900).
• The 2010–2019 decade was the warmest on record; 2020 tied as one of the hottest years.
• Atmospheric CO2 levels reached 417 ppm in 2021, a 49% increase from pre-industrial levels (280 ppm).
• Global sea levels have risen 8 inches (20 cm) since 1880, with projections of an increase between 1–4 feet by 2100.
• Deforestation and habitat destruction lead to biodiversity loss, with global forest loss estimated at 420 million hectares from 1990 to 2020.
• The World Wildlife Fund (WWF) indicates that 68% of global wildlife populations have declined between 1970 and 2020 mainly due to habitat loss and pollution.
• 1 million species are at risk of extinction in coming decades, according to the UN's IPBES.

Pollution and Its Impacts

• Pollution, including air, water, and soil contamination, poses significant environmental challenges.
• Industrial activity, transportation, agriculture, and inadequate waste management are major pollution sources.
• 92% of the global population lives in areas with air quality exceeding WHO guidelines; outdoor air pollution causes 4.2 million premature deaths annually.
• Water pollution from chemicals, plastics, and untreated sewage threatens human health and ecosystems; over 8 million tons of plastic waste enter oceans annually.
• 1 in 3 people worldwide lacks access to safe drinking water, and 2.2 billion lack safely managed sanitation services.
• Agricultural pollution from fertilizers and pesticides contributes to nutrient runoff, causing algal blooms and creating dead zones in aquatic ecosystems.

Efforts in Environmental Protection

• Numerous global initiatives and agreements have emerged to address environmental challenges.
• International collaborations, such as the Paris Agreement (2015), aim to combat climate change by uniting countries towards emission reduction, biodiversity conservation, and sustainability.
