Environmentalists study the best ways to protect the environment from harmful pollution. they also assist the general public in ways to learn to make the best use of natural resources.
Answer:
Being reliant on just one thing to drive the economy is a problem because even minor changes can lead to serious problems, so a solution is to develop other business sectors on time.
Explanation:
Most of the countries in the Middle East have their economies almost exclusively reliant on just one thing, that being the oil. They do possess some of the largest oil reserves in the world, but even though everything is going great with the trade of it for now and obtaining enormous amounts of money, that can easily change.
Being reliant on just one industry that is dependent on a single natural resource is a huge risk. If there are just slight changes in the price or demand goes down the economy immediately suffers badly. With the trend of the developed countries to gradually move away from fossil fuels, the Middle Eastern countries may soon face a huge economic problem. In order to try and prevent such a scenario, they can simply start to develop other business sectors, high profile ones that bring in lots of money, such as banking and tourism, so when the time comes that the oil is not so popular anymore, they will have other sectors that will drive their economy.

In general, de-extinction is not really a good idea.
Explanation:
De-extinction is a process through which organisms that lived in the past, but now are extinct, are resurrected, thus brought back into the environment. While this has only been a fantasy in the past, with the development of the technology it has actually become a real possibility. The opinions are divided about the de-extinction though, with lot of scientists and people supporting it, but as many also objecting it. The fact is that it is an unfamiliar zone, and it will be a big experiment if wild organisms are revived and set free, and it can go either way.
- The re-creation of an extinct species at letting it into the wild can bring many risks, be it direct danger, harming the environment, or it will just simply not be able to survive as the ecosystem is not the same as in the time when it lived.
- There can be big consequences by disturbing the natural food chains, thus causing some existing species to go extinct at the expense of the re-created species.
- Another major problem is that there is no guarantee about the behavior of the re-created species, as they can indeed behave as they are supposed to, but they can also have much more different behavior.

<u>Answer:</u>
<em>Ensuring a sustainable supply of food for the world's fast growing population is a major challenge. Food production is one of the key areas that require action, alongside issues of food consumption, nutrition and food security.
</em>
<em>
It is estimated that by 2050 the world's population will reach 9.1 billion (34% higher than today). Food production will need to increase by 70% to feed the larger and most likely more urban population.1 More food will have to be produced using less land. In addition water and energy will become limiting factors.
</em>
<em>
Added to the challenge is that sustainable food products need to be nutrient-dense to allow people to have a diverse diet that contains a balanced and adequate combination of energy and nutrients to support good health.</em>
