Main Causes and Consequences Substances such as waste, sewage, pesticides and other types of pollutants produced by human action cause serious effects on the environment.
ÁScaris lumbricoides: causative of ascariasis What they are - definition Human worms are diseases caused by worms (flatworms and nematellins) that parasitize the human body and cause some problems in the body's functioning.

The blood is formed in the bone marrow, being composed of blood plasma and figurative elements (red blood cells, leukocytes and platelets).
Soil Pollution: Cause of Various Environmental Problems Introduction Soil pollution causes various environmental problems, also affecting other segments of the environment such as springs, rivers, seas, water tables, etc. Main consequences: - The soil can be infertile for planting (defertilization); - Contamination of rivers, groundwater, springs, springs, lakes, etc; - Ecosystem imbalance through the extinction of plants and animals in the affected region; - Changes in soil density and consistency; - soil saturation; - Changes in soil typography; - Loss of natural drainage capacity; - Elevation in soil temperature when underground gas formation occurs (eg methane and carbon dioxide) - Impregnation of polluting substances; - Changes in the smell of the soil that makes up the soil; - Formation of sewage sludge on the surface; - Landslide in hills, caused by the infiltration of liquid pollutants.
Soil Contamination: A Serious Environmental Problem Soil Contamination - What it is Soil contamination is one of today's major environmental problems. For centuries man has been little concerned with the disposal of waste, chemicals and industrial waste. The result is a large amount of contaminated land that is unviable for farming or housing construction.
Eucalyptus: An Example of Amensalism What it is - Definition Also known as antibiosis, amensalism is an ecological relationship of interspecific character (between different species) and disharmonic (one species favors the relation to another). In amensalism, one species (animal or plant) harms another with the purpose of obtaining benefits for itself in relation to environmental resources.
Cerrado Biome: vegetation with grasses and shrubs. Introduction The word Cerrado comes from Spanish and means "closed". This word attempts to name a general feature of a dense shrub and grassy vegetation with short, winding trees, which are some of the main features of this biome.
Ecological successions: changes in biological communities Introduction - what they are, examples If we consult a Portuguese dictionary to know what a succession is, we will find something like this: series of events that follow or follow in a certain order. In this sense, ecological successions are sequential changes in both the structure and functionality of biological communities.
Toxoplasma gondii: sporozoan causing toxoplasmosis What they are - biological definition Sporozoans are endoparasites that have a complex life cycle, that is, they go through various stages during intracellular development. They have this name because they have special spores inside.

Parasite Brugia malayi (worm): Cause of Filariasis What is parasites - biological definition Parasites are living things that extract the resources needed for their survival from other organisms. There are several species of these beings that parasitize humans. Some are harmless, but many cause serious illness.
Microbiologist: works in health, research and food What is it? The microbiologist is a biology scientist who studies microorganisms (bacteria, viruses, unicellular algae, protozoa, among others). Therefore, he is a professional who works in the field of biological knowledge known as Microbiology.
