                                            Mangroves
1. Mangroves are the characteristic littoral plant formations of tropical and subtropical sheltered coastlines. Generally speaking, mangroves are trees and shrubs growing below the high-water level of spring tides. Their root systems are thus regularly inundated with saline water, even though it may be diluted due to freshwater surface run-offs and only flooded once or twice a year. Mangroves depend on terrestrial and tidal waters for their nourishment, and on coastal soils and silt deposits from upland erosion as substrate for support.
2. Mangroves are among the most productive terrestrial ecosystems and are a natural, renewable resource. However, the world's mangroves are beleaguered. Mangroves are losing their habitats as rivers are dammed, their waters diverted and the intertidal zone extensively developed for agriculture or aquaculture and generally dried up.
3. The depletion of mangroves is a cause of serious environmental and economic concern to many developing countries. This stems from the fact that at the interface between the sea and the land, mangroves play a pivotal role in moderating monsoonal tidal floods and in coastal protection. The continuing degradation and depletion of this vital resource will reduce not only terrestrial and aquatic production and wildlife habitats, but more importantly, the environmental stability of coastal forests that provide protection to inland agricultural crops and villages will become seriously impaired.

                                                   Botany
1. Botany is a branch of biology that involves the scientific study of plant life. Botany covers a wide range of scientific disciplines concerned with the study of plants, algae and fungi, including structure, growth, reproduction, metabolism, development, diseases, chemical properties, and evolutionary relationships between taxonomic groups. Today botanists study over 550,000 species of living organisms.
2. The study of plants is vital as they are a fundamental part of life on Earth, which generates oxygen, food, fibres, fuel and medicine that allow humans and other life forms to exist. Through photosynthesis, plants absorb carbon dioxide, a greenhouse gas that in large amounts can affect global climate. Additionally, plants allow us to produce food to feed an expanding population, produce medicine and materials, understand environmental changes more clearly.
3. Virtually all foods eaten come from plants, either directly from staple foods and other fruit and vegetables, or indirectly through livestock or other animals, which rely on plants for their nutrition. Plants are the fundamental base of nearly all food chains because they use the energy from the sun and nutrients from the soil and atmosphere, converting them into a form that can be consumed and utilized by animals.

Plasma Cutters
1. Modern industry depends on the manipulation of heavy metal and alloys. We need metals to build the tools and transportation necessary for day-to-day business. The reason is simple: metals are extremely strong and durable, so they're the logical choice for most things that need to be especially big, especially sturdy, or both.
2. The funny thing is that metal's strength is also a weakness: because metal is so good at resisting damage, it's very difficult to manipulate and form into specialized pieces. People can precisely cut and manipulate the metals using the plasma cutter. The plasma cutter is actually a common tool that has been around since World War II.
3. Plasma cutters are not the only devices to harness the power of plasma. Neon signs, fluorescent lighting and plasma displays, just to name a few, all rely on it to get the job done. These devices use "cool" plasma. Though cool plasma cannot be used to cut metals, it has tons of other useful applications.
Ответьте на вопрос
How is the effectiveness of plasma used in industry?
Metals can be manipulated both by plasma cutters and «cool» plasma.
In spite of having good characteristics metals’ drawback is in being manipulated primarily by plasma cutters.
Due to plasma cutters metals can be manipulated and formed.  
Plasma cutter is irreplaceable for manipulations with metals and “cool” plasma can be used for illumination.

Teaching
1. Good teaching is not a matter of techniques or methods, for, as curriculum is not education, so method is not teaching. Research indicates that good teachers cannot be differentiated on the basis of «teaching methods». The method is inseparable from the person of the teacher; in fact, the person of the teacher is more important than the method. 2. The good teacher is not an instructor, who simply provides information, facts and knowledge but a facilitator of learning for the student. Good teachers are not those who are simply experts in subject matter, or experts in teaching methods, or curriculum experts, or who utilize the most resources, such as audiovisual aids.
3. The best teacher is one who, through establishing a personal relationship, frees the student to learn. Learning can only take place in the student and the teacher can only create the conditions for learning. The atmosphere created by a good interpersonal relationship is the major condition for learning.
