Essential Environmental and Agricultural Concepts

Biomass Energy

Biomass energy is stored in living members of an ecosystem. It is organic matter produced by plants and other photosynthetic organisms.

Fossil Fuels Explained

Fossil fuels are geologic deposits of organic materials. These buried fuels are formed by the decomposition of ancient organisms over millions of years.

Wind Power Generation

Wind power is energy produced by a system of rotating blades (turbines) that harness the wind's kinetic energy.

Petroleum: Earth's Liquid Gold

Petroleum is a heterogeneous mixture of organic compounds, primarily hydrocarbons (hydrogen and carbon), found beneath the Earth's crust.

Understanding Natural Resources

Natural resources are materials or substances occurring in nature, of either biotic or abiotic origin, that are used to meet human needs or desires.

Nonrenewable Resources Defined

Nonrenewable resources are those that are inevitably going to be exhausted. They are considered nonrenewable because their regeneration occurs only through physical, chemical, and geological processes that take hundreds to millions of years.

Renewable Resources Explained

Renewable resources are forms of energy or materials that come from practically inexhaustible sources over the lifetime of a human being on Earth, and whose sustainable use is highly viable.

Aquaculture Practices

Aquaculture represents the cultivation and reproduction of aquatic resources with human intervention, utilizing various techniques and processes for culturing organisms in water.

Fundamentals of Agriculture

Agriculture is a set of techniques and knowledge used to cultivate land. It is a human activity involving the cultivation of different types of plants on the soil.

Biodiversity: Earth's Living Tapestry

Biodiversity is the totality of species that inhabit the planet and the relationships between them. It represents the actual or potential use of these living organisms.

The Hydrological Cycle

The hydrological cycle (or water cycle) is the continuous process that describes the movement of water on, above, and below the surface of the Earth, from precipitation to its return to the atmosphere.

Species in Danger of Extinction

A species in danger of extinction is an organism facing a very high risk of disappearing from the planet if its situation does not improve. This condition is often exacerbated by human activities.

Fishing: A Primary Human Activity

Fishing is an activity practiced by humans for millions of years, representing one of the primary extractive activities for food and resources.

The Green Revolution's Impact

The Green Revolution refers to the surprising progress in agricultural production, particularly of wheat and rice in Asia, beginning in the mid-1960s with the widespread application of agricultural science and technology.

Understanding Soil Composition

Soil is the surface layer of the Earth's crust, a complex mixture of organic matter, minerals, gases, liquids, and organisms that supports life.

Biological Pest Control

Biological control involves the release of natural enemies, such as predatory insects, to control pests. The goal is to manage pest populations without the predator itself becoming a plague.

Legal Control in Agriculture

Legal control refers to laws and regulations established by phytosanitary authorities in countries to require quarantine or regulate the movement of plant material, ensuring it does not enter the market if it poses a risk.

Cultural & Mechanical Control

Cultural and Mechanical Control involves practices such as collecting and storing healthy fruit or products, and the destruction of diseased or decadent plant material to prevent pest spread.

Natural Pest Control Methods

Natural Control aims for the least possible impact on the agro-ecosystem, leveraging existing natural enemies and climatic factors for pest management.

Chemical Pest Control

Chemical Control involves the use of chemical substances (pesticides, herbicides) to kill or repel pests and unwanted plants.

Ecotourism for Sustainable Development

Ecotourism is an alternative approach for achieving sustainable development. Its realization primarily emphasizes cultural and environmental sensitivity, promoting responsible travel to natural areas.
