Please help me guys!! Describe what role do humans have in protecting or changing this issue? Explain steps or plans you would implement.

Here are a few examples of ideas you could discuss:

Climate change

Habitat destruction

Invasive species

Pollution

Overpopulation

Overconsumption-exploitation

Humans can address and resolve the issues related to their environment and social problems.

Explanation:

Climate change: The climate change is caused by the seasonal change or due to human oriented activities like burning of fossil fuels related to liberation of green house gases this is related to global warming.

Human beings can take initiative of utilizing less fossil fuels, planting more trees so that they can absorb more carbon dioxide gas which is a chief green house gas responsible for raising the temperature.

Habitat destruction: The habitat destruction happens when the habitat is destroyed due to forest fire, volcanic eruption, earthquake or cyclone.

Humans can build strong houses by keeping in mind the hazards can influence the building where they are living.

Invasive species: The invasive species is the one which is introduced into the new environment due to human effort or naturally. The invasive species reduce the population of the native species by competing for resources.

The humans can determine whether the invasive species can possibly affect the members of the native species or not. Possible measures can be taken to reduce their population by selective hunting.

Pollution: The contamination of air, water, and soil by the action of polluting agents is called pollution.

The pollution can be reduced by reducing or restricting the sewage and industrial discharge in water, stopping or reducing the use of fossil fuel which on burning produce contaminating gases, and reducing the use of polythene bags which can contaminate the soil.

Overpopulation: The overpopulation is condition in which the population of the species exceeds the carrying capacity of the region. The carrying capacity is the ability of the ecosystem to sustain a particular number of members of the species depending upon the availability of resources.

The overpopulation in case of humans can be controlled by use of contraceptives, small family rule adaptability, and by stopping early marriage as this can offer long reproductive period to couples.

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
