The correct answer to this open question is the following.
Natural resources are non-renewable. People need to start acting responsibly to take care of the environment and not wasting valuable resources that will be much needed in the future.
In the case of water, there are countries and cities where people have to walk miles from their homes in order to get some fresh water for their families. We in the larger cities, just go to the faucet and drink and wast. That is not fair when poor people do not have this elemental resource.
We need to follow and respect conservation programs to protect the land and animals that give us the food we need. We order the food that we need and no more. No wasting. There are millions of people suffering too much hunger in the world.
And if we don't care about our limited resources, soon we will be facing scarcity of basic products. So let's be responsible and use only what we need.
