367 - How do human populations affect natural resources?

Human populations affect natural resources in many ways. Here are a few:

1. Water usage: More people means more water is used for drinking, washing, and growing food.
2. Food demand: Humans need food to survive, which leads to overfishing, deforestation, and overfarming of land.
3. Pollution: As the population grows, so does the amount of waste, pollution, and greenhouse gases released into the air, water, and soil.
4. Land use: Humans build homes, cities, and roads, taking up space that was once home to plants and animals, leading to habitat loss.
5. Resource depletion: As more people use natural resources, they become scarce and may run out, like fossil fuels, minerals, and timber.

If we're not careful, our actions can harm the environment and ultimately affect the resources we need to survive.
