Answer: Human beings use more and more natural resources because the population is growing, living standards are rising, and industry, cities and technology all need more raw materials and energy.
Every human activity depends on nature. We need soil and water to grow food, wood and minerals to build homes, coal, oil and gas for energy, and metals such as iron and copper for machines and tools. As the world's population increases, the demand for food, water, housing and clothing increases with it.
Development adds to this demand. People now want better houses, vehicles, electricity, electronic gadgets and a more comfortable life. Industries need larger amounts of raw materials and fuel, and growing cities need more land, water, roads and buildings. Modern farming also uses more water, fertilizers and land to feed everyone.
However, many resources such as coal, petroleum and minerals are limited, and even renewable resources like forests and groundwater are being used faster than they can be replaced. So, while we need these resources, we must use them wisely: reduce waste, reuse and recycle, and turn to renewable energy, so that future generations also have enough.
