The Environment is all the Natural Materials and Living things, including Sunlight, that surrounds as every day. In this environment we call things of value, Natural Resources. These resources are devided in two categories; Renewable Resources and Non- renewable Resources.
Renewable Resources like sunlight, forests, vegetation and fish are a few of these resources, because they come back naturally when used.
Non-Renewable Resources are important things in the environment that are limited and can be depleted, for example, fossils, fuels, coal, ores, etc.
Lightning is a resource that can kill and cause major damage, but still a natural thing in our environment.
The totality of all resources is defined as our Planetary Inheritance, and all included is our Environment.
To survive in this Environment all these resources are in need of the other and therefore an inter-relationship between them exist.
Everything around us, air, water trees, rivers, oceans, forests, plants, animals etc. is inclusive of our Environment.
These surroundings, Environment, can be influenced by natural changes. For example, Change in climate, and natural disasters which include, Earthquake, Typhoon, and Flooding.
Humans’ are causing damage to the environment on a very large scale; including Greenhouse gasses caused by human activities. Global warming is worsened daily by the extensive use of cars, releasing gasses, Pesticides, being used for Agriculture and killing insects, naming only a few.
Our Atmosphere, that is our air, is a chaotic system, and even the smallest of changes can affect it largely. Even human activities such as Agriculture and industries have inadvertently modified weather patterns.
All living things and all non-living things are encompassed in the natural Environment. They interact with each other and need each other. There are many things we can do to help our Environment and even make it better. Simple small things, like, driving less, recycling of reusable
5 Natural Disasters that have a huge influence on our environment
Drought – No rainfall for a long period of time. All water sources, dams and reservoirs are influenced. No water to be seen.
Flood – Torrential rains for long periods causing rivers and dams to overflow, the strong currents taking with them everything in their wake; e.g. Houses, Vegetation, trees etc.
Tidal Wave – Enormous wave, usually caused by an earthquake beneath sea level, sweeping inland, leveling everything as it goes.
Earthquake – The earth shifts and moves causing everything on the surface to shake and roll. Can be caused by a fault in earth plates or even underground mining activities.
Volcanic Eruption – Worldwide there are a few active Volcanoes that can erupt causing Lava Rivers that consume vegetation, houses, etc. as well as volcanic ash filling the atmosphere.
5 Human Activities that is destroying the Natural Environment
Water Pollution – Water resources get dirtied by rubbish thrown in it, illegal dumping of substances, Businesses or Mines pumping dirty water in rivers, dams, streams, and even in the Ocean.
Air Pollution – Exhaust fumes of motor cars, busses, etc. Coal fires, Pesticides that is used to kill insects, Aerosol that can be extremely toxic when sprayed in the air.
Soil Pollution – Illegal waste dumping, Synthetic Chemicals. Major contributors to this are Agricultural byproducts, industrial operations and household chemicals.
Inefficient use of Land – Natural spaces are being invaded by suburban developments, forests has to make room for agriculture and where mining activities took away natural habitat, it might never return.
Invasive Species – Plant or Animal Species brought to a new area where they never were before, are called non-native and exotic. These plants or animals can flourish and take over, and even destroy native species. They become invasive.
All over the world, Countries work together to find solutions to improve pollution and focus on preserving the sources there still is.

Coastal Erosion is caused mostly through the Forces of Nature. The Seasons run their natural course, regardless of human planning. Although human planning may cause problems when Nature has to find a way to by-pass their efforts in order to flow naturally!
Tons of sand swept away by Spring Tides.
Big seas with large waves.
Seasonal storms with wind and rains.
These are a few of nature’s ways that causes erosion and change in coastal formations.
Most inhabitants near the shore assumes that the shoreline never changes, but billions of years of Geological History, shows that Coastal Areas are the least constant features on the Planet’s surface.
Human measures were taken to safeguard homes, businesses, holiday resorts, swimming areas and even mining and agricultural activities.
4 of these human measures are:
Artificial sand berns; artificially produced sand is used to build different types of structures.
Breakwaters; rock or concrete armor units placed strategically to break the force of the waves.
Groynes; similar to breakwaters. Groynes can be placed in a long row or in separate shorter rows.
Seawalls; there function is to contain soil and prevent it from eroding in the water.
These are all Engineered Structures trying to fix reclining shore surfaces and beach fronts. But, reducing erosion at one point only causes more erosion at another. Fixed structures cannot survive when the shoreline moves inevitably.
Research showed that the sea surface temperature is higher, the sea level is higher and that more frequent and intense storms can be expected.
3 Key actions to be taken before future planning and safeguarding that will identify the most effective approach to alleviate further damage.
Collect, record and analyze coastal data before planning and undertaking coastal protection initiatives.
Implement recommendations from planning done after research and follow instructions regarding all control structures and beach nourishment work
Ensure that all future ocean and beach fortification and preventative structures are approved by central City Planning Committee before commencing in building it.
The outcome will be:
Beaches and dunes are managed to protect public property
Private property owners will understand their responsibilities in protecting their own properties.
3. A rock sea wall along urban sections of the shoreline will protect infrastructure.
4. All new development will be set back to allow the natural coastal processes.
The coast is a Dynamic, sometimes very inhospitable environment. A Holistic Approach, understanding and taking in account all influences and their long-term movement, should be taken.
Manly was named by Captain Arthur Phillip, after having an unexpected meeting with a local Aboriginal clan. A Military party was scouting for fresh water when they encountered members of the Guringai clan, feasting on a Whale.
