Space Apps Challenge 2018

From the beginning of the earth the living organisms live in a symbiotic relation with the surrounding environment,with all the changes that happen all the time because of many different reasons,some are external and some are internal.in the old time when the dinosaurs were exist a meteor hit the earth and end the life on it that's an external sunden factor of environmental changes.one of the internal factor is volcanos.

Changes on the long term made this planet viable til now.but now we should ask ourselves,are we gonna survive from the future disasters? Is there a new hand involved in the environmental changes nowadays?

Our ecosystem affects the environment and be affected by it.plants,for example,takes the CO2 from the surrounding air and use it for photosynthesis.on the other hand plants are food for some creatures.also our ecosystem adapt with the environment and its changes,such as weather variation.

As we said the environment around us changes on and on, and that affect us and the other living things.so we're trying to study how,and find a suitable solutions for the problems in such cases.

One way we get the studies and information is NASA`s data which obtained by satellites that give a daily data about the situation of earth.the most important satellites are “Terra” and “Aqua”.Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days,acquiring data in 36 spectral bands .the other way is the potential sources of local citizen science observation.but today we`re gonna match between them both.

The biggest problem which takes a large potential of researches recently and we observe it daily is the effects of the greenhouse Gases emission on the living things (humans,animals and plants).and trying to find a particular solutions to this impacts.

The planet’s surface has already warmed by 1 degree Celsius (1.8 degrees Fahrenheit) and could see a catastrophic 1.5 C (2.7 F) increase between 2030 and 2052, scientists say.

Causes of greenhouse gas emission:

1. Burning of Fossil Fuels: Fossil fuels like coal, oil and natural gas have become an integral part of our life. They are used on large basis to produce electricity and for transportation. When they are burnt, the carbon stored inside them is released which combines with oxygen in the air to create carbon dioxide. With the increase in the population, the number of vehicles have also increased and this has resulted in increase in the pollution in the atmosphere. When these vehicles run, they release carbon dioxide, which is one the main gas responsible for increase in greenhouse effect.

Deforestation:Large scale development has resulted in cutting down of trees and forests which has forced people to look for alternate places for living. When the wood is burnt, the stored carbon in converted back into carbon dioxide.

3. Increase in Population: Over the last few decades, there have been huge increase in the population. Now, this has resulted in increased demand for food, cloth and shelter. New manufacturing hubs have come up cities and towns that release some harmful gases into the atmosphere which increases the greenhouse effect. Also, more people means more usage of fossil fuels which in turn has aggravated the problem.

4. Farming: Nitrous oxide is one the greenhouse gas that is used in fertilizer and contributes to greenhouse effect which in turn leads to global warming.

5. Industrial Waste and Landfills: Industries which are involved in cement production, fertilizers, coal mining activities, oil extraction produce harmful greenhouse gases. Also, landfills filled with garbage produce carbon dioxide and methane gas contributing significantly to greenhouse effect.
