Environmental impact assessment (EIA) = ∑(E × I × M)
Carrying capacity (K) = (r × N)/(dN/dt)
Biochemical oxygen demand (BOD) = (DO × (1 - (t/tₙ))) / t
Air quality index (AQI) = (I × (C/C₀)) + (I₀ × (1 - (C/C₀)))

🪤 The 5 Mistakes That Cost Marks

Not understanding the difference between climate change and global warming
Confusing sustainable development with environmental conservation
Not knowing the hierarchy of waste management: reduce, reuse, recycle
Ignoring the impact of population growth on environmental degradation
Not being able to calculate the carbon footprint of a given process

✏️ 3 Solved PYQs

What is the ma∈ cause of ozone layer depletion ∈ the stratosphere? Answer: Chlorofluorocarbons (CFCs)
Calculate the carrying capacity of a population with a growth rate of 2% per year and a death rate of 1% per year Answer: K = (0.02 × N)/(0.01 × N) = 2
What is the air quality index (AQI) for a city with a PM2.5 concentration of 50 μg/m³? Answer: AQI = (I × (50/35)) + (I₀ × (1 - (50/35))) = 100

🧠 The One Thing Most Students Get Wrong

Most students think that environmental conservation is only about saving endangered species, but it's actually about preserving the entire ecosystem, including plants, animals, and microorganisms

👁️ Ayush's Note

Always remember the 3Rs: reduce, reuse, recycle, and the 4Cs: conserve, conserve, conserve, conserve
Make a list of all the environmental issues and their causes, effects, and solutions
Practice calculating the carbon footprint and ecological footprint of different processes and products
Learn about the different types of pollution: air, water, soil, noise, and thermal
Understand the concept of sustainable development and its importance ∈ environmental conservation

📝 Practice MCQs

1. What is the ma∈ cause of acid ra∈?

A) Emissions from vehicles

B) Industrial waste

C) Burning of fossil fuels

D) All of the above

Answer: D) Explanation: Acid ra∈ is caused by the emission of pollutants such as sulfur dioxide and nitrogen oxides into the atmosphere, which can come from various sources including vehicles, industrial waste, and the burning of fossil fuels.

2. Which of the following is a renewable source of energy?

A) Coal

B) Oil

C) Natural gas

D) Solar energy

Answer: D) Explanation: Solar energy is a renewable source of energy that is sustainable and non-polluting, unlike coal, oil, and natural gas which are non-renewable and contribute to climate change.

3. What is the purpose of the Kyoto Protocol?

A) To reduce greenhouse gas emissions

B) To conserve biodiversity

C) To protect the ozone layer

D) To promote sustainable development

Answer: A) Explanation: The Kyoto Protocol is an international treaty that aims to reduce greenhouse gas emissions and mitigate the effects of climate change.

4. Which of the following is an example of a non-point source of pollution?

A) Industrial effluent

B) Agricultural runoff

C) Domestic sewage

D) Vehicle emissions

Answer: B) Explanation: Agricultural runoff is an example of a non-point source of pollution, which is a type of pollution that comes from a wide area and is not confined to a specific point of orig∈.

5. What is the term for the movement of pollutants from one environment to another?

A) Bioaccumulation

B) Biomagnification

C) Transboundary pollution

D) Environmental degradation

Answer: C) Explanation: Transboundary pollution refers to the movement of pollutants from one environment to another, such as from air to water or from soil to groundwater.
