What are the causes of destruction of natural resources?

Causes of Depletion of Natural Resources
  • Overpopulation. The total global population is more than seven billion people. …
  • Poor Farming Practices. …
  • Logging. …
  • Overconsumption of Natural Resources. …
  • Pollution. …
  • Industrial and Technological Development.

Why is resource depletion a problem?

Depletion of finite resources such as oil, gas, useable water or minerals is likely to impact on world GDP well before the worst impacts of global warming. The two together are likely to constrain world food production seriously, particularly in countries with high population densities or insufficient fertile lands.

What will happen if natural resources run out?

Like trees, plants feed us and give us the oxygen we breathe—and if they were to run out, humans and animals would starve and suffocate. According to New Scientist, oxygen would remain in the atmosphere for quite a while, but we would run out of food long before we’d run out of air.

How do renewable resources affect the environment?

Electricity from renewable energy sources produces between 90-99% less greenhouse gases (GHGs) compared with coal-fired plants and causes 70-90% less pollution. … Focusing on renewable energy sources other than fossil fuels and coals might help in avoiding environmental impacts, specifically from air pollution and GHGs.

Which energy source causes the least pollution?

Nuclear energy has one of the lowest environmental impacts of all energy sources, comparable with the total impacts of wind and solar. It doesn’t emit air pollution, it safely keeps its waste out of the environment and it requires a very small amount of land.

What are the disadvantages of natural resources?

  • Renewable resources are only available in certain parts of the world, eg sunny places.
  • Non renewable resources are scarce and will run out.
  • Non renewable resources cause pollution.
  • Renewable resources are expensive.

What are the advantages and disadvantages of non-conventional sources of energy Class 8?
