- - - - The causes of these changes and their effects on living things. :
        
        Geological records show that there have been a number of large variations in the Earth's climate. These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2).
        
        Global climate change has typically occurred very slowly, over thousands or millions of years. However, research shows that the current climate is changing more rapidly than shown in geological records.
        
        Changes to living things: Overhunting and overfishing can harm or destroy populations of organisms. ... Humans can also accidentally introduce new organisms into ecosystems. These organisms can use up food, space, and water that other organisms need. These animals or plants are called invasive species.
        
        Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

        Global warming
        
        Global warming! ( Global warming is when greenhouse gases get released into the atmosphere and warm the Earth, some greenhouse gases are Methane, Carbon dioxide, Sulfer.

        All of these reasons cause extinction of many animals like the Polar bears, North Atlantic cod and the Adeili Penguin.
        
        Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents.
      - How humans can make necessary precautions or actions. :
        
        Walk, cycle or take public transport
        The world’s roads are clogged with vehicles, most of them burning diesel or petrol. Walking or riding a bike instead of driving will reduce greenhouse gas emissions – and help your health and fitness. For longer distances, consider taking a train or bus. And carpool whenever possible.
        
        Eat more vegetables
        Eating more vegetables, fruits, whole grains, legumes, nuts and seeds, and less meat and dairy, can significantly lower your environmental impact. Producing plant-based foods generally results in fewer greenhouse gas emissions and requires less energy, land and water.
        
        Consider your travel
        Aeroplanes burn large amounts of fossil fuels, producing significant greenhouse gas emissions. That makes taking fewer flights one of the fastest ways to reduce your environmental impact. When you can, meet virtually, take a train or skip that long-distance trip altogether.
        
        Throw away less food
        When you throw food away, you're also wasting the resources and energy that were used to grow, produce, package and transport it. And when food rots in a landfill, it produces methane, a powerful greenhouse gas. So use what you buy and compost any leftovers.
        
        Reduce, reuse, repair & recycle
        Electronics, clothes and other items we buy cause carbon emissions at each point in production, from the extraction of raw materials to manufacturing and transporting goods to market. To protect our climate, buy fewer things, shop second-hand, repair what you can and recycle.
        
        Change your home's source of energy
        Ask your utility company if your home energy comes from oil, coal or gas. If possible, see if you can switch to renewable sources such as wind or solar. Or install solar panels on your roof to generate energy for your home.
        
        Switch to an electric vehicle
        If you plan to buy a car, consider going electric, with more and cheaper models coming on the market. Even if they still run on electricity produced from fossil fuels, electric cars help reduce air pollution and cause significantly fewer greenhouse gas emissions than petrol or diesel-powered vehicles.
        
        Speak up
        Speak up and get others to join in taking action. It's one of the quickest and most effective ways to make a difference. Talk to your neighbors, colleagues, friends, and family. Let business owners know you support bold changes. Appeal to local and world leaders to act now.
        
        Choose eco-friendly products
        Everything we spend money on affects the planet. You have the power to choose which goods and services you support. To reduce your environmental impact, buy local and seasonal foods, and choose products from companies who use resources responsibly and are committed to cutting their gas emissions and waste.
        
        Save energy at home
        Much of our electricity and heat is powered by coal, oil and gas. Use less energy by lowering your heating and cooling, switching to LED light bulbs and energy-efficient electric appliances, washing your laundry with cold water or hanging things to dry instead of using a dryer.
