Answer:
With the advancements in the field of science, biologists can propose a number of ways to help people who live in dry, hot areas.
Explanation:
The growth of plants on hot, dry lands can now be made possible through modern biotechnology techniques. Biologists can try to grow plants on these lands which will have the capability to grow while consuming less water. Genetically engineered crops that will produce more food and require less water and could withstand harsh environments could be made. Biologists can also start growing trees that can withstand the dry conditions through selective breeding.
