Marine pollution, which occurs in various ways, is the entry of chemicals, particles, industrial, agricultural and domestic wastes into the seas. The sources of marine pollution are land and human origin.
The Pollution Occurring in the Seas:
1-Flowing from settlements and industrial facilities along the sea shores
2-From platforms and pipelines in the seas
3-It consists of ships and marine vehicles.
4- You can see the number and species of living life in the sea decrease
5-With port activities and sea traffic
6-They reach the sea via rivers and streams

The reasons why we chose this pollution are:
•Over three billion people depend on marine and coastal biodiversity for their livelihoods.
•Oceans contain nearly 200,000 identified species, but actual numbers may lie in the millions.
•Marine fisheries directly or indirectly employ over 200 million people.
•Open Ocean sites show current levels of acidity have increased by 26 per cent since the start of the Industrial Revolution.
•Oceans absorb about 30 per cent of carbon dioxide produced by humans, buffering the impacts of global warming.
•Subsidies for fishing are contributing to the rapid depletion of many fish species and are preventing efforts to save and restore global fisheries and related jobs, causing ocean fisheries to generate US$50 billion less per year than they could.

This is a big submarine that cleans sea surface without hurting any animal. This machine has 4 different pipes.
One of this pipe is collecting plastics, one of is metals , one of is glasses, one of is collecting other soils and it
store every different meterials in different tanks. When the tanks are full the submarine goes up the water surface and
it unloads all the soils in the recycling places. After that , it goes under water again and keep doing its duty.
It scan underwater try to clean sea like that. Its a machine working without humans thats why it can stay underwater until
his tanks are full. His size is big but it doesn't hurt any sea animal because before it cleans an area it propagades
a magnectic wave to make the sea animals run so it can clean the area easily.

It is one of the most dangerous eco problems in the world. Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles.
Some air pollutants are poisonous. Inhaling them can increase the chance you'll have health problems. People with heart or lung disease, older adults and children are at greater risk from air pollution.
The air inside buildings is also can be polluted.

We have choosen it because:
-Smog can irritate the eyes and throat and also damage the lungs—especially of people who work or exercise outside, children, and senior citizens. It’s even worse for people who have asthma or allergies—these extra pollutants only intensify their symptoms and can trigger asthma attacks.
-Air pollution causes damage to crops, animals, forests, and bodies of water. It also contributes to the depletion of the ozone layer, which protects the Earth from the sun's UV rays.
-Another negative effect of air pollution is the formation of acid rain, which harms trees, soils, rivers, and wildlife.

The strongest power is the knowledge!!!
Our machine will search for the most polluted areas of our country and will call environmental inspection.
Also we are thinking about other actions that our machine will be able to do.

Soil pollution is defined as the build-up in soils of persistent toxic compounds, chemicals, salts, radioactive materials, or disease causing agents, which have adverse effects on plant growth and animal health.

Our machine is also able to monitor soil quality. The sensor monitors when the soil is dry and we need to water the plant. Now we are testing it on houseplants, but we hope that later we can use it to larger areas.

Land pollution is the destruction of the earth’s land surfaces, often directly or indirectly as a result of man’s activities and their misuse of land resources.
It occurs when waste is not disposed of properly, or when humans throw chemicals onto the soil.
There are different types of land pollution:
Solid Waste
These include all the various kinds of rubbish we make at home, school, hospitals, market and workplaces. Things like paper, plastic containers, bottles, cans, food and even used cars and broken electronic goods, broken furniture and hospital waste are all examples of solid waste.
Pesticides and Fertilizers
Many farming activities engage in the application of fertilizers, pesticides and insecticides for higher crop yield. Sometimes, insects and small animals are killed and bigger animals that eat tiny animals (as in food chains) are also harmed.
Chemicals
Chemical and nuclear power plants produce waste materials that have to be stored somewhere. In many cases, they are stored in an environmentally safe way, but there are some that find their way into landfills and other less safe storage facilities. Sometimes they also find their way into leaking pipes and gutters. They end up polluting soils and making crops harmful to our health.
Deforestation
Humans depend on trees for many things including life. Trees absorb carbon dioxide (a greenhouse gas) from the air and enrich the air with Oxygen, which is needed for life. Trees provide wood for humans and a habitat to many land animals, insects and birds.

Especially in big cities people produce lots of waste and all these waste materials pollute the environment. We thought that we should find a way to reduce those waste materials.
Also as the cities get bigger and bigger it became harder to see plants and trees, everywhere is full of big buildings. People are unhappy in those buildings. Especially these days because of the corona virus we are trapped in our houses hoping to meet the beautiful plants and trees around our city.

First of all our robot works with green energy. While going around the city it is going to collect the plastic wastes. It will heat them in its tank with the energy from the sun and turn them into oil. It is going to use that oil to produce energy that will help to work all day long.
It will also collect the organic wastes in the garbage cans and mix it with soil and then plant seeds all around the city in order to make it greener.
It is a very big robot which also has a filtering system to clean the air. It is not so easy to clean the air but it tries to do its best.
Our robot detects the production of chemicals, pesticides and send warning messages to the city council  about the detected problems.
