<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>

Answer:
E. Atmosphere composed mainly of hydrogen and helium
Explanation:
- As the Jovian planets are gas giants they are composed of the high-speed atmospheric flows
, hosted by rapidly rotating planet
. They have dense volumes of gas and are filled with the hydrogen and the helium gases and huge gravitation potential allows them to have large storms and have thick bands of clouds and also being far located from the sun they have retained their atmosphere for long periods.
Tropical places are hot because the humidity coming from the moisture of the plants and water are heated by the sun on the top layer of the tropical zone. The climate varies little in rain forest. There are five layers in the tropic trees so it's so thick that barely any light come through. This is also why vines grow up the trees so they can reach the sunlight to get nutrients. Also, the tropics are near the equator and that also causes the heat. The polars are cold because they barely get any sun heat to melt the snow or warm it up. The polars are melting due to certain chemicals and gasses in the atmosphere. also known as global warming. Hope that was helpful!

Theater
The presentation of written word, known as "theater," began in Athens and diffused to other parts of the ancient Greek empire.
Government
In 508 B.C. it also gave birth to the world's first democracy. Democracy is a system of government in which citizens elect representatives to advocate for them in the government.
Architecture and art- During the Classical and Hellenistic periods of Greek art, the ancient Greeks idolized the human form. During this time, advances in sculpting and painting techniques were made that would influence the Italian Renaissance centuries later. Once classical Greek art was rediscovered, Italian artists began depicting the beauty of the human body as the Greeks once did. Along with modern religion themes of the time, Italian painters also painted scenes of popular Greek myths and stories.
