Chapter 1 Lesson 1 - What is environmental science? It is a field that integrates scientific methods and disciplines to understand and address real world environmental challenges. - Most significant environmental problems. 1. Forest destruction 2. Global warming 3. Air pollution - How can automobiles emission contribute to global warming? Motor vehicles exhaust produce greenhouse gases. Such as (co2, co) these gases prevent sun heat to reach the earth ground, this will increase the temperature of the atmosphere. \-\-\-- solution: use electric car or use mass transit (public transport) - What is ecology? It is the study of the interaction between living things and nonliving (environment). \-\-\-- it is the foundation of environmental science. - What is the difference between environmentalism and ecology? Ecology is the study of relationships between organisms, whereas environmentalism is a way to protect our environment from its current threats. - What are the main environmental problems? 1. Resource depletion: the random usage of nonrenewable resources. (fossil fuel) 2. Pollution: the alterity of the characteristics of air, water, and soil. 3. Hunter gathers: the killing of animals in a random way -- and using forest destruction and explosions to do it. 4. Loss of biodiversity: number and variety of species that live in an area. - What is an agriculture revolution? Process of growing, breeding, and caring for plants, and animals that are used for food, clothing, housing, and transportation. - What is an industrial revolution? The transition from creating goods by hand to using machines. Chapter 1 Lesson 2 Supply and demand: non-renewable resources. - The greater the demand for a limited supply of something is, the more that thing is worth. Ex: gold What is the difference between developed and developing countries? - Developed countries- leading countries. 1. High Yearly salary 2. Slower Population growth 3. Diverse industrial economics 4. Stronger social support system - Developing countries- 1. Lower Yearly salary 2. Rapid Population growth 3. Simple and agriculture-based economics. Sustainability -- is the condition in which human needs are met is such a way the human population can survive indefinitely. - Example- clean water, varieties of food, advanced healthcare How to live 100% sustainably? 1. Use what you already have. 2. Buy only what you need. 3. Take care of what you have. How do we create a sustainable world? 1. Think twice before shopping. 2. Go plastic free. 3. Boycott products that endanger wildlife What does a sustainable world look like? Clean water, sanitation, decent work & economic growth. What is the goal of a sustainable world? They aim to transform our world. They are a call to action to end poverty and protect the planet and ensure that all people enjoy health. Chapter 4 Lesson 1 - What is an ecosystem? All the organisms living in area together with their physical environment. The interaction between living and non-living. - The components of an ecosystem: 1. Biotic factors: living parts of an ecosystem, including all the plants and animals. 2. Abiotic factors: nonliving parts of the ecosystem, including air, water, rocks, sand, and light. - Species: a group of organisms that can make to producer fertile offspring such as humans and animals. - Population: all members of the same species that live in the same place at all sometime. - Communities: a group of various species that live in the same place and interact with each other. - What is the difference between communities and ecosystem? A community is different from an ecosystem because a community is made up only of biotic components. - Habitat: 1. The place an organism lives. 2. It is important to an organism because it has the biotic and abiotic factors the organism needs to survive. Chapter 4 Lesson 2 - Analogous: different structure with the same function. - Homologous: similar structure with different functions. - Vestigial: various cells, tissues and organs in a body which no longer serve a function. - Natural selection: organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. - Adaptation: a modification of an organism or its parts that makes it more fit for existence. - Evolution: the process by which species adapt over time in response to their changing environment. - Isolation: the state of being in a place or situation is separate from others.
