Environmental degradation and conservation.

1. BIOSPHERE IN BALANCE

TROPHIC PYRAMIDS

• Each bar in the pyramid represents a different class of organism.
• The leangth of each bar indicates the amount of biomass each level contains.

PRODUCERS

• Highest biomass
• Their bar for the trophic level is the biggest.

PRIMARY CONSUMERS

• Hearvibores.
• They feed on plants.

SECONDARY CONSUMERS

• Organisms that eat primary consumers for energy.
• They can either be carnivores or omnivores.

TERTIARY CONSUMERS

• They are predators
• Usually tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material.

THE CONSEQUENCES OF VERY RAPID POPULATION GROWTH

• Destruction of habitats
• Pests and plages
• Bioaccomulation

2.HYDROSPHERE INBALANCE

*INDLAND WATER*

SPRINKLE IRRIGATION

DRAINGE OF WETLANDS

POLLUTION IN RIVERS AND LAKES

*MARINE WATER*

RISSING LEVEL WATER

OIL SILKS

FLOATING ISLANDS OF RUBBISH

DISCAHRGES AND DRAINGAE

SALINISATION

3. ATMOSPHERIC INBLANCE

*AIR POLLUTION*

Excess substances such as carbon dioxide cause an imbalance in the natural composition of air, contaminating gases those that either affect our health or cause climate change. Knowing wind direction can help us predict which areas will be affected.

*THE EFECTS OF SO2 AND NO2*

• They produce the acid rain, that cause serius dameges.
• Acid cause desgradation of the buildings.
• It cause smog when the particles sostain in the air.

THE "OZONE HOLE"

The ozone layer is a layer that protect us from the ultraviolet radiation. The hole in the ozone has been produced by the CFCs that are in the seprays in general, in the smoke, in the exhaust gases... The hole is in the polar part, but it can spread if we humans continue to pollute.
