How would you reply to someone who argues that we should not worry about the effects that human activities have on natural syste
svp [43]

Answer:

It is partially true, "life finds a way" but human activities have already made some irreversible damage to the world.

Explanation:

In a Hypotethic scenario in which Humans are extinct nature Will eventually, start succession processes in urban areas and after many years depending on the erosional resistance of the materials nature will erase many of the buildings around the world ( 500 years for metal). Water bodies will eventually decontaminate trough the water cycle and be filled with organisms, contamination due to petrol can also be reverted through natural chemical processes with oxygen.

But human activities like mining are irreversible, for the earth, it is impossible to recover its shape, the materials already extracted and soil nutrients that ran out due to the use of chemicals.

The acceleration of the climate change due to human activities is for sure the biggest wound we have made to the world, this is an irreversible acceleration to a natural process.

The Arts

Whether you are looking for music, a vibrant nightlife scene, museums or exhibitions, you will find plenty of interesting places to visit, especially in the capital, Lisbon. Have a look at the Lisbon Cultural Agenda for more detailed information about what’s on.

Festivals

Romarias (pilgrimages) are local religious festivals that honour the patron saint of a particular area throughout Portugal. If you happen to be in an area during these celebrations, be sure to check them out! Watch a solemn procession, observe the local religious gowns and absorb the pious atmosphere before taking part in the festivities that follow.

Regional Costumes

Traditional garments such as the red and the green stocking cap of the Alentejo cattleman still exist and the samarra (a short jacket with a collar of fox fur) still survive.

Regional costumes can also be seen in the northern Minho province at weddings and other festivals. Women dress in extremely colourful and rich costumes, often in red and white, and wear several long ornate gold necklaces, covering their heads with a scarf.

In Trás-os-Montes e Alto Douro shepherds wear straw cloaks, while the wearing of black for protracted periods of mourning is common especially in villages in the interior of Portugal.

In Madeira, the regional dresses can often be seen at local markets and flower stalls.
