Earth and Human Activity
The impact of human activities on Earth is huge. Although we exploit the resources of the Earth to live and grow, the processes can spoil the environment as well. Let us look at the effects we have on the planet, and how we can help.
☣️ 1. Pollution
Pollution is introducing harmful substances into the environment, causing destruction.
Types of Pollution:
- Air Pollution: Vehicles and factories emit harmful gases.
- Water Pollution: Waste and chemicals harm aquatic life.
- Land Pollution: Litter and improper waste disposal damage land ecosystems.
Effects of Pollution:
- Harmful to human health and animals.
- Destroys ecosystems and wildlife habitats.
- Contributes to climate change and global warming.
How to Reduce Pollution:
- Recycle, reuse, and reduce waste.
- Use eco-friendly products and clean energy.
- Support laws that reduce pollution.
🌡️ 2. Global Warming
Global warming is the rise in Earth’s temperature due to human activities.
Causes:
- Burning fossil fuels like coal and oil.
- Deforestation reduces carbon absorption.
- Industrial and agricultural gas emissions.
Effects:
- Melting ice caps and rising sea levels.
- Extreme weather: hurricanes, floods, droughts.
- Loss of habitats for many species.
What We Can Do:
- Use solar, wind, and renewable energy.
- Buy energy-efficient appliances and cars.
- Plant trees to reduce carbon dioxide.
⛏️ 3. Natural Resources
Natural resources are Earth's materials we use for food, energy, and living.
Types of Resources:
- Renewable: Sunlight, wind, water – naturally restored.
- Non-Renewable: Fossil fuels and minerals – limited and hard to replace.
Importance:
- Fuel economies, build homes, power cities.
- Support food, transportation, and technology.
Conservation Tips:
- Prevent waste through mindful usage.
- Buy recyclable and less resource-heavy items.
- Switch to renewable energy sources.
